I am trying to disassemble a TR4 gearbox. This gearbox has no serial number stamped on it. It is a full syncro box with the constant thickness mounting flange. My problem is that I cannot get the counter shaft out of the box. The rear small thrust washer will not separate from the counter shaft. The tab on the washer is lined up with the slot in the case but will not slide out from the counter shaft. It will slide around but not come out. It feels like there is something on the thrust washer that is hung up on the inner bore and will not allow the thrust washer to be slid out from between the case and the counter shaft. When I try to pry the thrust washer out from the counter shaft the entire counter shaft moves and binds in the case. There is some clearance between the thrust washer and the counter shaft. I can insert a thin piece of steel in the clearance but it will not go completely through the clearance, it is hitting something. I am assuming that the small thrust washer must be extracted first then the counter shaft will have enough clearance to get it out of the box. I have had both the large and small thrust washers tabs aligned with the slots in the case but still no luck. Am I missing something? Thanks for your help.
